Technical Overview
2015 Kawasaki Z 250SL ABS Technical Analysis & Specification Breakdown
Built around Kawasaki's naked motorcycle platform, the 2015 Kawasaki Z 250SL ABS relies on a 249 cc (15.2 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 32 HP (23.4 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 128.5 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Z 250SL ABS measures 150 kg (331 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.69 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,330 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 170 km/h (106 mph).
